Out in the Cold: Australia's involvement in the Korean War

Weaponry and communications

Bofors gun

Firing 40 mm calibre ammunition, the Swedish-designed Bofors gun
was a fully automatic cannon intended primarily for use against aircraft.
It was first fitted to Australian ships during the Second World War, quickly
becoming standard for most ships. Some ships of the RAN are still fitted
with Bofors guns. In the Korean War, there was little call for the use
of the Bofors, but with a range of over two kilometres it could also be
used in shore bombardments. During her time as part of the Han
River blockade, HMAS Murchison engaged enemy positions ashore
on several occasions with her Bofors guns.
